I would generally bet flop. You have to b/f, but since your 3-bet range AK, AQ, TT-AA then I don´t really think you get bluffraised that often and it makes your hand easier to play. If you check then you´re always guessing if he is bluffing or valuebetting. Also If you bet flop, you can bet turn for value on T, K and c/c A+ you don´t let yourself bluffed out and you don´t give lower pp-s free cards
